| 中文摘要: |
| 为改善LY12CZ合金焊接后的机械性能和抗腐蚀性能，采用激光表面焊接技术对Al-Mg-Sc合金和LY12CZ进行对焊。分析了金相组织、显微硬度、拉伸强度以及抗腐蚀性能，试验结果表明：采用激光焊接技术可以对Al-Mg-Sc合金和LY12CZ进行对焊，不仅可保证较高的强度，还可以获得晶粒细小、硬度高于基体的强化层，并且由于镁、钪合金元素的加入还可以提高铝合金的抗腐蚀性能。 |
| 英文摘要: |
| Laser welding of Al-Mg-Sc alloy and LY12CZ has been studied in order to increase the strength properties and corrosion resistance. Microstructure, hardness, tensile strength and corrosion resistance have been analyzed. The experimental results show that using laser welding technology not only can weld alloys but also can get smaller grain size, strength and hardness are higher than the substrate, and the adding of Mg and Sc elements can also raise corrosion resistance of Al alloy. |
